O-Phosphorylethanolamine
O-Phosphorylethanolamine. Alternative Names: O-Phosphoethanolamine; 2-Aminoethyl dihydrogen phosphate. CAS No. 1071-23-4. Purity: 98+%. Product ID: ACM1071234-1. Molecular formula: C2H8NO4P. Mole weight: 141.06. Alfa Chemistry - ISO 9001:32057 Certified.
O-phosphoserine sulfhydrylase
A pyridoxal-phosphate protein. The enzyme from Aeropyrum pernix acts on both O-phospho-L-serine and O3-acetyl-L-serine, in contrast with EC 2.5.1.47, cysteine synthase, which acts only on O3-acetyl-L-serine. Group: Enzymes. Synonyms: O-phosphoserine(thiol)-lyase. Enzyme Commission Number: EC 2.5.1.65. CAS No. 1071505-11-7. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-2802; O-phosphoserine sulfhydrylase; EC 2.5.1.65; 1071505-11-7; O-phosphoserine(thiol)-lyase. Cat No: EXWM-2802.
O-phosphoseryl-tRNASec kinase
In archaea and eukarya selenocysteine formation is achieved by a two-step process: O-phosphoseryl-tRNASec kinase (PSTK) phosphorylates the endogenous L-seryl-tRNASec to O-phospho-L-seryl-tRNASec, and then this misacylated amino acid-tRNA species is converted to L-selenocysteinyl-tRNASec by EC 2.9.1.2 (Sep-tRNA:Sec-tRNA synthase). Group: Enzymes. Synonyms: PSTK; phosphoseryl-tRNA[Ser]Sec kinase; phosphoseryl-tRNASec kinase. Enzyme Commission Number: EC 2.7.1.164. CAS No. 91273-83-5. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-2994; O-phosphoseryl-tRNASec kinase; EC 2.7.1.164; 91273-83-5; PSTK; phosphoseryl-tRNA[Ser]Sec kinase; phosphoseryl-tRNASec kinase. Cat No: EXWM-2994.
